The American marten or Martes americana, also called American pine marten is a species of North American mammal, a member of the family Mustelidae. The species is sometimes referred to as simply the pine marten. The name “pine marten” is derived from the common name of the distinct Eurasian species Martes martes.

Their head is usually lighter than the rest of their body, while the tail and legs are darker. American marten usually have a characteristic throat and chest bib ranging in color from pale straw to vivid orange.
